1. Steel is non-combustible
Steel can’t burn, because it contains no elements that can serve as fuel. Steel provides no means for a fire to start, does not contribute to fire growth or fire spread and does not contribute to the generation of smoke and toxic combustion products in fires.
2. Steel maintains its non-combustibility
Steel remains non-combustible throughout the entire lifecycle of the building — during building construction, occupation and future renovation and repair.
3. Steel-framed buildings lower the fire risk to workers and occupants
Decades of research into understanding the behavior of structural steel components when exposed to fire has given designers the confidence to engineer buildings that will provide optimum fire safety.
Fire resistance-rated walls and floors help limit or slow the spread of flames in a building and maintain the integrity of the structure.
4. Steel-framed buildings lower the impact on municipal fire services
Recent building code changes that permit increased building heights and areas for wood framing have had devastating results. A rash of catastrophic, multi-story, wood-frame building fires in Canada and the United States have destroyed entire building complexes.
Such fires have challenged the resources of fire services. They have prompted several municipalities to implement site-safety regulations during the construction of combustible buildings that will ultimately increase the construction costs and timeframes of projects. Some cities, such as the affluent Atlanta suburb of Sandy Springs, are working to ban combustible framing above three stories.
5. Steel-framed buildings tend to cost less to insure
Insurers traditionally offer steel-framed structures lower builders risk and general liability premiums compared to structures framed with wood.
